The invention discloses a flying body with curved-surface micro groove structures and a manufacturing method of the flying body. The flying body comprises a cylinder and a conical head, wherein multiple micro grooves are uniformly distributed at intervals along the axial section of the curved surface of the conical head, and the curved surface is a two-dimensional rotating surface in a parabolic surface or an elliptical surface. During
machining, the manufacturing method comprises the steps of firstly
machining a cylindrical material into the flying body which is provided with the conical head and has a rough curved surface with a curved surface profile; then
machining the rough curved surface into a smooth curved surface along the curved surface profile by utilizing a corner of the annular end surface of a fine-grained
diamond grinding wheel; finally axially steering the
grinding wheel, enabling the
grinding wheel to be vertical to a workpiece rotating shaft or to be in a certain inclination angle relative to the workpiece rotating shaft, enabling a workpiece to be fixed, and carrying out radial feeding along the radial direction of the smooth curved surface profile by utilizing a V-shaped pointed end of the
diamond grinding wheel in high-speed rotation so as to
machine the micro grooves in the curved surface. According to the manufacturing method disclosed by the invention, the smooth curved surface with the regular and controllable micro groove structures is machined on the flying body, the air resistance of the flying body can be reduced, the
laser scattering can be enhanced, and resistance reduction and
invisibility of flying can be finally realized.
